Well the postal worker was here and didn't leave me with OS4. So, I am stuck with 3.9 for Christmas, but hopefully not the rest of the year!
Normally when I get something shipped from the UK, it takes a week. I assume the delay this time is due to other holiday shipping.
What's the point of tracking? Royal Mail says they gave it to USPS. USPS says they recieved notice that Royal Mail is going to give it to them.
